UK unveils £2.5bn AI Sovereign Fund and quantum scale-up
Coordinated investment package aims to accelerate AI adoption and deploy large-scale quantum systems to drive long-term economic growth
The UK is doubling down on AI and quantum with a £2.5 billion push to scale both technologies at pace. The plan pairs a new Sovereign AI Fund with a major expansion of quantum infrastructure and procurement.
The coordinated announcement, made on March 17, signals a more interventionist approach to technology policy, with ministers aiming to anchor high-growth companies domestically while building national capability in next-generation computing systems.
Chancellor of the Exchequer Rachel Reeves said the government faces a strategic choice in shaping emerging technologies, warning against leaving development solely to market forces or foreign players.
She said the UK aims to achieve the fastest adoption of AI in the G7 while maintaining domestic control over its direction.
She said quantum computing represents a generational leap in capability, with the potential to transform industries ranging from healthcare to energy. The government intends to ensure these technologies are developed, deployed, and commercialized within the UK.
Sovereign AI push
The first strand of the announcement focuses on strengthening the UK’s position in artificial intelligence through a Sovereign AI Fund and broader ecosystem support.
The government will launch a £500 million Sovereign AI Fund in April to provide capital, compute resources, and infrastructure support to high-potential British AI firms. The initiative aims to help companies scale domestically while remaining competitive globally.
The fund is part of a broader policy shift to align AI development with national priorities, particularly in economic resilience, public services, and industrial competitiveness.
Key elements of the AI package include:
• £500 million Sovereign AI Fund to support scaling companies
• Part of a wider £2.5 billion combined AI and quantum investment package
• Target to achieve the fastest AI adoption in the G7
• Access to compute infrastructure and technical resources
• Support to anchor high-growth AI firms in the UK
• Integration with broader industrial strategy focused on digital technologies
• Alignment with regional growth and skills development initiatives
• Backing for startups and scale-ups across the UK’s AI ecosystem
The UK already has a strong foundation in AI, with a high concentration of startups and research talent.
Since 2020, more AI companies have been founded per capita in Britain than in any other European country, reinforcing its position as a leading innovation hub.
The government’s strategy seeks to convert that early-stage advantage into sustained commercial leadership, ensuring that companies not only launch in the UK but also grow and remain headquartered there.
Quantum scale-up
Alongside AI, the government has outlined an ambitious plan to establish the UK as a global leader in quantum computing, committing up to £2 billion to the sector.
Central to this effort is a first-of-its-kind procurement programme, branded “ProQure: Scaling UK Quantum Computing,” which will support the development and deployment of large-scale quantum computers in the UK by the early 2030s.
Under the ProQure programme, companies will develop prototype systems for evaluation, with the most promising progressing to larger-scale machines integrated into national infrastructure. The approach is designed to stimulate demand, unlock private investment, and accelerate the transition from research to commercial deployment.
The programme bridges the gap between research and commercialization by providing guaranteed demand for emerging technologies, enabling companies to raise capital and accelerate development.
Key components of the quantum investment include:
• Up to £1 billion for procurement of commercial-scale quantum computers
• Over £500 million for quantum computing development and applications
• More than £400 million for sensing, navigation, and supporting infrastructure
• £125 million for quantum networking and £205 million for sensing technologies
• £13.8 million for five National Quantum Research Hubs
• Additional funding for skills, commercialization, and infrastructure programs
The initiative will invite companies to develop prototype systems, which will then be evaluated before scaling into operational machines for public and commercial use.
The government expects quantum technologies to deliver significant economic benefits, including improved drug discovery, more efficient energy systems, and enhanced national security capabilities. Estimates suggest the sector could generate more than £200 billion in economic impact over the coming decades.
The UK already hosts one of the world’s most advanced quantum ecosystems, supported by more than a decade of public investment and a growing base of private-sector participation. The new funding aims to consolidate that position by accelerating large-scale deployment.
Industry response
Industry stakeholders broadly welcomed the announcement, while emphasizing the need for supporting infrastructure alongside hardware investment.
“Quantum computing is moving from promise to practical impact - unlocking new computational capabilities that can help solve complex real-world problems,” said Philip Intallura, HSBC Group Head of Quantum Technologies. “It will also reshape how we think about cybersecurity, making it vital that we invest now in quantum-safe approaches.”
He added that it is encouraging to see the UK government backing the skills, research and scale-up needed to turn world-class science into deployable capability and long-term economic growth.
Dan Holme, chief executive of Qoro Quantum, said the ProQure programme addresses a critical gap in demand but warned that hardware alone will not deliver value.
“The ProQure programme is exactly the right move, but the procurement of quantum hardware only delivers value if there is an intelligent software layer to orchestrate workloads across those machines,” he said. “Without the proper software, these early quantum machines are incredibly difficult and expensive to operate. It’d be like putting a manual gearbox into a modern F1 car—you’re not maximizing the potential of the hardware.”
Professor Callum Littlejohns, deputy director of CORNERSTONE, said the focus on scaling and deployment strengthens the strategy and that infrastructure will be key to supporting domestic firms.
“It’s right that the UK government has put scaling at the heart of its quantum leap scheme,” he said. “To nurture homegrown firms, we need the right infrastructure in place to ensure companies can access the capabilities they need to grow.”
The combined announcements reflect a broader policy direction that places advanced computing at the center of economic strategy, with the government seeking to align investment, infrastructure, and industry development under a unified framework.
As global competition intensifies across AI and quantum technologies, the UK’s approach reflects a renewed emphasis on sovereign capability, balancing open innovation with strategic control over critical technological assets.
